At least 40 people have been killed and several hundred more injured after an explosion and fire at Iran's largest port, according to state media.
The blast, at the Shahid Rajaei container hub near the southern city of Bandar Abbas, happened on Saturday as Iran held a third round of talks with the US in Oman about Tehran's nuclear programme.
Shipping containers burned, goods inside were badly damaged and the explosion was so powerful that windows several miles away were shattered, reports said.
Helicopters and aircraft dumped water from the air on the blaze and by Sunday afternoon it was 90% extinguished, the head of Iran's Red Crescent Society told state media.
Officials said port activities had resumed in unaffected parts of Shahid Rajaei.
Out of the 752 people who had received treatment for their injuries, 190 were still being treated in medical centres on Sunday, according to Iran's crisis management organisation.
Chemicals at the port were suspected to have worsened the blast, but the exact cause of the explosion was not clear.
Iran's defence ministry denied international media reports that the explosion may be connected to the mishandling of solid fuel used for missiles.
The reports were "aligned with enemy psyops [psychological operations]", according to a ministry spokesperson, who told state TV the blast-hit area did not contain any military cargo.

According to the Associated Press, British security company Ambrey said that the port in March received sodium perchlorate, which is used to propel ballistic missiles and the mishandling of which could have led to the explosion.
The Financial Times previously reported two Iranian vessels had shipped from China enough of the ingredient to propel up to 260 mid-range missiles.
It was reportedly to help Tehran replenish stocks after its missile attacks on Israel in 2024.
Iran's military has sought to deny the delivery of sodium perchlorate from China.
Iran's state-run Irna news agency reported on Sunday that Russian President Vladimir Putin deployed several emergency aircraft to Bandar Abbas to provide help.
